Regex filter for duration is not working properly

[unknown-73]

Background:

We want to filter the alerts based on the duration. Alters that have a duration under 10 min should not be displayed in nagstamon.
For this scenario we tried multiple regex filters:

1. m|s --> we tried this because the other filters were not working either
2. s --> we tried this because the other filters were not working either
3. s$|^\d{1} m$ --> this was the actual filter, but it does not always work

With these filters applied we are still getting alerts for services or hosts with a duration of ex. "241s" ; "39.4s" ; "7m"

[unknown-73]

Is there any solution to this problem?

@unknown-73 with the correct regex ist should work. Maybe you can find some with https://regex101.com ?
